Shock-resistant optical glass construction

• Compatible with a Haida 100 or 100-Pro Filter Holder
• Darkens bright areas of an image, such as skies, while leaving the remainder of the frame unaffected
• Provides up to a 3-stop reduction of light in selective areas
• Hard-edged line of transition between the dense and clear areas
• Useful for images that feature horizons or any hard transition between the sky and land
• Filter does not affect the overall coloration of the image
• 10 layers of anti-reflective nano coatings on each glass surface prevent internal ghosting and reflections, while further enhancing clarity and color fidelity
• 10 additional scratch-resistant hydrophobic coatings on each glass surface further protect the filter substrate and result in an improved beading effect when in contact with water or oil for greater cleaning efficiency
• Rounded edges for easier placement within a compatible filter holder slot
• When combined with a compatible filter holder, included gasket helps to prevent light from coming in between the filter and the lens behind it, which can have an unwanted effect on exposure
• Metallic filter case for storage and transport
